Almost Security of Cryptographic Boolean Functions

Kaoru Kurosawa

Abstract

$P C (l)$ of order $k$ is one of the most general cryptographic criteria of secure Boolean functions. In this paper, we introduce its $ϵ$ -almost version. The new definition requires {\it only} that is {\it almost} uniformly distiributed (while the original definition of of order requires that it is {\it strictly} uniformly distiributed). We next show its construciton. Better parameters are then obtained than normal of order functions.
